Well, Frederick's has more slutty looking stuff and La Perla is expensive. You could get something classy from either or trashy from either, but I think the idea is a "have you gotten it on looking like a stripper" and "have you done the deed looking like a classy lingerie model."
If that's the case, then I'll add 2 and say I'm at 30!
Now knowing about Fredericks and la Perla, if we don't count name brands, then I can jump up to 42 because I have quite the collection and some would probably fit into the categories mentioned.
And I agree about sex in the ocean, however I picture NY water which I have a hard enough time swimming in let alone fucking. Maybe somewhere with clear water and I might consider it.
34. It may go up by a few (I can't believe I don't think I've done it in the rain??) but the days for most of those things are long gone. Hard to imagine having group sex right now!
